I luckily hardly use any Windows so I refrain from commenting on its (maintenance) quality. But I have to use another MS product daily: Teams. It's a product with very poor usability. Even simple things like tracking which message you have read and which one you haven't don't get better upgrade after upgrade. I am sure they have a huge development budget and tons of paid developers. The number of paid developers can be completely uncorrelated to quality. (I am sure zulip has just a little fraction of paid developers, but it is a program in the same domain that works muuuch better.)
